Hi all, I have a 2005 e55 amg and I am getting a dms ecu/pulley upgrade. I went to have a pre upgrade dyno at Dyno Demon's dyno dynamics rolling road. Unfortunately, the experienced technician couldn't get the esp to stay off, even after it was turned off he was feeling braking of the rear wheels so couldn't do the test. Has anyone else had this problem and any suggestions to get round it? Thanks
